Hello!

At commit https://github.com/torvalds/linux/commit/113d1dd9c8ea2186d56a641a787e2588673c9c32#diff-545daf8a36330dbe9e9bca384f13ff7dc878284c411be77102044393eab7e310 (Seek for blk_queue_dma_alignment in code) this function was removed from all drivers, including mainline rts5208/rtsx.c file.

That said, I applied this patch:

And module compiled. Since my hardware is the rtsx usb, this module still not serving me, but may help other people

Hi, I've got a compilation error with a 6.10.6 kernel :

/var/lib/dkms/rts5227/1.08/build/rtsx.c: In function 'slave_configure':

Downgrading to a 6.9.10 kernel is OK.

Dear Robert, could you update the package to point at this repo: https://github.com/strahl/rts5227-dkms It appears to work fine on recent kernels. If you have no time for this I can maintain this package, ping me on github alexpyattaev.

I patched the driver in https://github.com/strahl/rts5227-dkms for 5.16 here: https://github.com/ewisuri/rts5227-dkms

i've tried replacing https://github.com/Zibri/Realtek-rts5229-linux-driver with https://github.com/strahl/rts5227-dkms in source, and 5229 with 5227 in $sourceDir/blacklist-rts5229.conf, but it still does not compile

hello! since the first kernel 5.16 I'm getting this error and sd card stops being mounted after cold/hard boot.

==> dkms install --no-depmod rts5227/1.07 -k 5.16.1-arch1-1 Deprecated feature: REMAKE_INITRD Error!

@Shara lspci output is not a valid way to debug these kind of issues."Unassigned class" string also appears on working devices.

@LittleHuba this issue was fixed and can't reproduce. Please reinstall the package and everything should work flawlessly

Build issue with newer kernels:
